The Window Object
Example
// Navigation
window.location.href = "https://example.com";
window.history.back();
// Dimensions
console.log(window.innerWidth, window.innerHeight);
// Timers
const timer = window.setTimeout(() => console.log("3 seconds"), 3000);
window.clearTimeout(timer); Pro Tip
You can omit the window. prefix since it is implicit — but being explicit helps when window properties might be shadowed.
